The 20 degree angle I mentioned was meant to describe the direction of the force I need to apply to make the channel go out, it's not quite that bad. But if I were to try to perform the fix you just described I'd be looking for a new mp3 player :) It seems like the application of the force is just barely pushing the headphone connection off of the left channel contact, but while the player is stationary I have no problems. I bought an L-adapter for my good headphones and made a little mod to the neoprene case which keeps the headphone connection isolated, and this pretty much works but there's nothing worse than getting into your music and losing a channel, major buzzkill. If there is no easy fix that doesn't require the soldering iron, (which seems doubtful) I'll make sure to give the tech at the electronics repair store a copy of your instructions.
